 * Zweck:        Verwaltet die IST-Erfassung, Eingabe in Monaten
 * Aufruf:       Durch Menuepunkt "IST-Erfassung" in "forms.php->menu.inc"
 * Beschreibung: Dieses Modul verwaltet die IST-Erfassung in ganzen Monaten.
 *               Es koennen also nur PT's fuer jeweils 1 Monat eingegeben
 *               werden. Dabei werden diese Eingaben intern so gespeichert,
 *               dass die PT's auf die Tage des Monats aufgeteilt werden,
 *               so das es scheint als waeren die Eingaben pro Tag in Stunden
 *               erfolgt.
